Acceptance Guideline For Longitudinal Cracking In Reinforced Concrete Pipe
Reinforced concrete pipe, when designed in accordance with AS/NZS4058 and AS/NZS3725 can last for over 100 years. However, when the synergy required between manufacturers, designers, installers and asset managers is not met, the integrity of the concrete pipe may be affected.
Database or spreadsheet. What’s the difference, anyway?
To address this question it’s easiest to look at estimating from a historical perspective: Once upon a time, every contractor created estimates by hand. He/she would pull out a pad of paper and pencil, jot down some figures line by line, then sum up each item to achieve the estimate. This was a simple and effective way to create a bid, but human error, inflexibility, and time consumption left plenty of room for improvement.
The Determination of Damage to Reinforced Concrete Beams Designed to 1972 Ministry of Works Design Codes
Currently there is no prescribed method for determining the amount of damage sustained by a reinforced concrete structure designed to pre 1972 New Zealand design standards during an earthquake. One of the key features of these designs is the amount of shear damage that is observed and the lack of knowledge today, in assessing and repairing this form of damage.
Law relating to contracting
The law states that a contract shall be deemed legal if it is drawn up between consenting parties who accept it as complete and unconditional and some external manifestation of assent communicates the acceptance of an offer.(Burrows, Finn, & Todd, 2202, p. 60)

| Basecourse Production Rates | We have found these production rates a good rule of thumb for the construction of Basecourse Urban environment: Spread & Compact Production = 30m3/hr Trimming Production = 250m2/hr Rural environment: Spread & Compact Production = 50m3/hr Trimming Production = 350m2/hr
